MVVM Survival Guide for Enterprise Architectures in Silverlight and WPF

Appendix B. Binding at a Glance

By Muhammad Shujaat Siddiqi

Basics

• Binding is a markup extension.
• Binding target must be a dependency property.
• Binding source must be public property.
• Binding Target: Where Binding is defined [Petzold].
• Use MultiBinding for multiple Binding sources for the same target. Changes in any of them cause target to be updated
• If an entire object is used as a binding source then binding can use the implicit/explicit DataTemplate defined for the type, otherwise, it uses the ToString() method for the type.
• In a partial trust environment, we cannot bind to dynamic object property or CLR property of a non-public class.
